Yes, regular bubbles have a nice sheen of their own, but adding a few drops of liquid food coloring to the mixture really makes a big difference. A note, though, make sure you make this one outside, away from anything that you don't want stained (cars, patios, decks, etc.).
Knowledge is intelligent; it is here for a purpose. Knowledge is the part of your mind that is spiritual and permanent. It is the part of your mind that knows who you are and why you have come here, who you must reach and what you must accomplish. Knowledge is within you now, but you cannot lay hold to it.
For knowledge, of course. To have knowledge means to know or be aware of things. Knowledge is understanding gained through learning or experience. You read a recipe to gain knowledge about baking rhubarb pie. When it burns in the oven, experience gives you the knowledge that you need to stop doing three things at once. Fields like biology, math, art, medicine, and others have huge bodies of knowledge. Knowledge can mean information and also deeper understanding.
